Dual‐Metal Co‐Doping Strategy Enhances the Hydrogen Dissociation and Hydrogen Release Performance of LiBH4 Assisted by Ensemble Learning

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT LiBH4 has drawn significant attention due to its high theoretical hydrogen storage capacity of 18.5 wt%, yet its practical application is hindered by the harsh dehydrogenation conditions. This paper proposes a strategy integrating ensemble learning with density functional theory (EL–DFT) for rapidly screening modified LiBH4 systems that ...

Tuning Y‐Mg Supports for Improved Ni‐Catalyzed NH3 Decomposition: Structural Modulation and Mechanistic Insights

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...

人乳头瘤病毒线性杂交分型技术的建立及评价

open access: yesZhongguo shiyan zhenduanxue, 2010
目的建立人乳头瘤病毒(Human papillomavirus,HPV)线性探针反向杂交(1ine probe assay,LiPA)基因分型技术,通过基因测序技术对LiPA分型检测的效果进行评价。方法利用基因工具软件比对HPV L1基因,设计HPV型别的基因探针,手工将探针点样于条形尼龙膜上,再进行LiPA杂交分型。LiPA检测的样本结果与HPV基因测序的结果进行比较,以评价LiPA检测的效果。结果74例利用LiPA成功地作出了基因分型,其中单独一型HPV感染为40例,涉及13种不同基因型HPV ...
